nostalgia for the future
In the current era, instead of wanting to go back to an imaginary golden age of hand crafting, we can combine the thinking and crafting. We can go into the future shaped by now and the past.
轉場儀式
關門，過橋，開燈
很多時候，在進入一個狀態轉換時，容易感到卡住。例如事情做得不順、要準備上班，或者在需要精神集中處理事情與想要休息放鬆之間，反而卡在中間，沒辦法真正切換。
為了改善這種狀況，轉場儀式可以分為三個階段：
- 關門
將手邊的東西卸下來，可以透過寫下來的方式，把腦中的思緒放掉。 - 過橋（Physical Change）
這是一個物理上的轉換。例如坐下來冷靜一下，或是做一些讓身體感知改變的動作，讓自己安靜下來。 - 開燈
確認下一個階段要做什麼。將自己的身份以及想以什麼樣的狀態呈現，實際講出來，這能幫助自己清空先前的狀態，讓大腦切換到新的工作或休息模式，而不會一直停在卡住的狀態。
tragedy of the common
When a resource is shared by everyone, people tend to overuse it because nobody owns it. If people view it as free, they might as well use as much of it as possible so “not to waste” it without regarding other people’s need of it.
Elinor Ostrom won Nobel Prize showing community management (without government) works better than people thought in fixing this issue.
muon tomography
Muon from the space can pass through open space but absorb by heavy materials. So detecting the shadow, people can map out the structures. Some examples are mapping the open space inside pyramid, monitoring the magma inside volcano, and tracking the dangerous fuel in the broken nuclear reactor.
